Abstract
PURPOSES End-stage liver and kidney disease is an indication for simultaneous liver and kidney transplantation. However, in countries where deceased donor transplantation is not well established, living donor liver transplantation (LDLT) is a realistic option for patients on hemodialysis (HD). We investigated the outcomes of LDLT for patients on HD. METHODS We conducted a retrospective multicenter survey of patients on chronic HD who underwent LDLT in East Asian countries. The characteristics of donors and recipients and the short and long-term outcomes were analyzed. RESULTS Between 2001 and 2021, 45 patients on HD underwent LDLT and 11 of these patients also underwent kidney transplantation (KT). The overall survival rate at 5 years of the 34 patients who underwent only LDLT was 44.5%. Multivariate analysis identified a low graft recipient weight ratio (< 1%) (p = 0.048) and long HD duration (≥ 10 years) (p = 0.046) as independent predictors of poor overall survival. The major complication was posttransplant bleeding, which occurred in12 patients (35%). CONCLUSION It is important to establish the indications for LDLT, taking into consideration graft size and HD duration in candidate patients on HD.

Abstract
Backgrounds/Aims Challenges arise when translating pure laparoscopic donor right hepatectomy (PLDRH) results from Asian to Western donors, due to differences in body mass index (BMI). This study compares the outcomes of PLDRH and conventional open donor right hepatectomy (CDRH) in donors with BMI over 30. Methods Medical records of live liver donors (BMI > 30) undergoing right hepatectomy (2010-2021) were compared: 25 PLDRH cases vs. 19 CDRH cases. Donor and recipient demographics, operative details, and outcomes were analyzed. Results PLDRH and CDRH had similar donor and recipient characteristics. PLDRH had longer liver removal and warm ischemic times, but a shorter post-liver removal duration than CDRH. Donor complication rates were comparable, with the highest complication being grade IIIa in PLDRH, necessitating needle aspiration for biloma on postoperative day 11. Fortunately, this donor fully recovered without additional treatment. No complications exceeding Clavien-Dindo grade IIIa occurred in either group. Recipient outcomes between the groups were similar. Conclusions This study supports PLDRH as a viable option for donors with BMI over 30, challenging the notion that high BMI should deter considering PLDRH. The findings provide valuable insights into the safety and feasibility of PLDRH, encouraging further exploration of this technique in diverse donor populations.

Abstract
Following its initial execution in November 2015, pure laparoscopic donor hepatectomy (PLDH) has gained acceptance as a conventional practice at Seoul National University Hospital (SNUH). It is noteworthy that a significant proportion of cases entail full right hepatectomies, which are acknowledged to be technically demanding. As expertise and knowledge have been accrued, the pure laparoscopic technique has been extended to encompass liver recipients as a viable option in SNUH. The aim of this review is to present the developmental progression of PLDH, with a focus on pure laparoscopic donor right hepatectomy (PLDRH), at SNUH. This includes the standardization process, which can be achieved by sharing the hospital's accumulated experience and previous reports. Various types of graft, including full right, left, left lateral section, and monosegment, were procured by pure laparoscopic technique. The criteria for selection were expanded to include donors with variations in the anatomy of the portal vein and bile duct. Additionally, the procedure of PLDRH was determined to be safe and viable for donors with high body mass index and larger graft weight. In conclusion, this review demonstrates the alterations implemented throughout our evolution from restricted to inclusive criteria for donor selection, leading to a complete shift from open surgery to pure laparoscopic procedures in donor hepatectomy and eventually pure laparoscopic living donor liver transplantation (LDLT) in recipient.

Abstract
BACKGROUND Gut microbial dysbiosis is implicated in chronic liver disease and hepatocellular carcinoma (HCC), but the role of microbiomes from various body sites remains unexplored. We assessed disease-specific alterations in the urinary microbiome in HCC patients, investigating their potential as diagnostic biomarkers. METHODS We performed cross-sectional analyses of urine samples from 471 HCC patients and 397 healthy controls and validated the results in an independent cohort of 164 HCC patients and 164 healthy controls. Urinary microbiomes were analyzed by 16S rRNA gene sequencing. A microbial marker-based model distinguishing HCC from controls was built based on logistic regression, and its performance was tested. RESULTS Microbial diversity was significantly reduced in the HCC patients compared with the controls. There were significant differences in the abundances of various bacteria correlated with HCC, thus defining a urinary microbiome-derived signature of HCC. We developed nine HCC-associated genera-based models with robust diagnostic accuracy (area under the curve [AUC], 0.89; balanced accuracy, 81.2%). In the validation, this model detected HCC with an AUC of 0.94 and an accuracy of 88.4%. CONCLUSIONS The urinary microbiome might be a potential biomarker for the detection of HCC. Further clinical testing and validation of these results are needed in prospective studies.

Abstract
Liver transplantation is a highly complex and challenging field of clinical practice. Although it was originally developed in western countries, it has been further advanced in Asian countries through the use of living donor liver transplantation. This method of transplantation is the only available option in many countries in the Asia-Pacific region due to the lack of deceased organ donation. As a result of this clinical situation, there is a growing need for guidelines that are specific to the Asia-Pacific region. These guidelines provide comprehensive recommendations for evidence-based management throughout the entire process of liver transplantation, covering both deceased and living donor liver transplantation. In addition, the development of these guidelines has been a collaborative effort between medical professionals from various countries in the region. This has allowed for the inclusion of diverse perspectives and experiences, leading to a more comprehensive and effective set of guidelines.

Abstract
Calcineurin inhibitors (CNIs) are essential in liver transplantation (LT); however, their long-term use leads to various adverse effects. The anti-intercellular adhesion molecule (ICAM)-1 monoclonal antibody MD3 is a potential alternative to CNI. Despite its promising results with short-term therapy, overcoming the challenge of chronic rejection remains important. Thus, we aimed to investigate the outcomes of long-term MD3 therapy with monthly MD3 monomaintenance in nonhuman primate LT models. Rhesus macaques underwent major histocompatibility complex-mismatched allogeneic LT. The conventional immunosuppression group (Con-IS, n = 4) received steroid, tacrolimus, and sirolimus by 4 months posttransplantation. The induction MD3 group (IN-MD3, n = 5) received short-term MD3 therapy for 3 months with Con-IS. The maintenance MD3 group (MA-MD3, n = 4) received MD3 for 3 months, monthly doses by 2 years, and then quarterly. The MA-MD3 group exhibited stable liver function without overt infection and had significantly better liver allograft survival than the IN-MD3 group. Development of donor-specific antibody and chronic rejection were suppressed in the MA-MD3 group but not in the IN-MD3 group. Donor-specific T cell responses were attenuated in the MA-MD3 group. In conclusion, MD3 monomaintenance therapy without maintenance CNI provides long-term liver allograft survival by suppressing chronic rejection, offering a potential breakthrough for future human trials.

Abstract
BACKGROUND Although the adoption of pure laparoscopic donor hepatectomy has expanded driven by considerations of donor cosmesis and function, the criteria for selecting candidates for pure laparoscopic donor right hepatectomy (PLDRH) continue to be debated. This study aimed to delineate the distinctive characteristics of donors and recipients who underwent conventional open-donor right hepatectomy (CDRH) during the era of PLDRH. MATERIALS AND METHODS We conducted a retrospective review of a prospectively collected single-center database encompassing all right hepatectomies at OOOO from April 2016 to December 2021, a period during which there were no absolute contraindications for PLDRH. RESULTS During the exclusive PLDRH period, there were still 63 cases of CDRH alongside 362 cases of PLDRH. The CDRH donors were older, had a lower estimated remnant liver volume, and a higher incidence of expected multiple openings in the portal vein and bile duct based on preoperative imaging compared with PLDRH donors. In the subgroup analysis, including only donors meeting two or more criteria (age ≥40 y, estimated remnant liver volume ≥35%, or multiple anticipated vessel openings), recipients in the PLDRH group exhibited significantly more early major complications (P=0.029) compared with those in the CDRH group. CONCLUSION As PLDRH gains traction in practice, it is essential to acknowledge that specific donor conditions, such as advanced age, limited remnant liver volume, and anticipation of multiple portal or bile duct openings, may merit contemplating CDRH as a means of optimizing recipient outcomes.

Abstract
In living-donor liver transplantation, biliary complications including bile leaks and biliary anastomotic strictures remain significant challenges, with incidences varying across different centers. This multicentric retrospective study (2016-2020) included 3633 adult patients from 18 centers and aimed to identify risk factors for these biliary complications and their impact on patient survival. Incidences of bile leaks and biliary strictures were 11.4% and 20.6%, respectively. Key risk factors for bile leaks included multiple bile duct anastomoses (odds ratio, [OR] 1.8), Roux-en-Y hepaticojejunostomy (OR, 1.4), and a history of major abdominal surgery (OR, 1.4). For biliary anastomotic strictures, risk factors were ABO incompatibility (OR, 1.4), blood loss >1 L (OR, 1.4), and previous abdominal surgery (OR, 1.7). Patients experiencing biliary complications had extended hospital stays, increased incidence of major complications, and higher comprehensive complication index scores. The impact on graft survival became evident after accounting for immortal time bias using time-dependent covariate survival analysis. Bile leaks and biliary anastomotic strictures were associated with adjusted hazard ratios of 1.7 and 1.8 for graft survival, respectively. The study underscores the importance of minimizing these risks through careful donor selection and preoperative planning, as biliary complications significantly affect graft survival, despite the availability of effective treatments.

Abstract
Pure laparoscopic donor hepatectomy (PLDH) has become a routine procedure at Seoul National University Hospital, and the pure laparoscopic method is now being applied to liver recipients as well. This study aimed to review the procedure and outcomes of PLDH to identify any areas that required improvement. Data from 556 donors who underwent PLDH between November 2015 and December 2021 and their recipients were retrospectively reviewed. Among these, 541 patients underwent pure laparoscopic donor right hepatectomy (PLDRH). The mean hospital stay of the donor was 7.2 days, and the rate of grade I, II, IIIa, and IIIb complications was 2.2%, 2.7%, 1.3%, and 0.9%, respectively, without any irreversible disabilities or mortalities. The most common early and late major complications in the recipient were intraabdominal bleeding (n = 47, 8.5%) and biliary problems (n = 198, 35.6%), respectively. Analysis of the PLDRH procedure showed that operative time, liver removal time, warm ischemic time, Δhemoglobin%, Δtotal bilirubin%, and postoperative hospital stay decreased significantly as the number of cases accumulated. In conclusion, the operative outcomes of PLDRH improved as the number of cases increased. However, continuous caution is needed because major complications still occur in donors and recipients even after hundreds of cases.

Abstract
Purpose Incisional hernia (IH) is a common complication after liver transplantation (LT) with an incidence rate of 5% to 46%. This retrospective study aimed to evaluate the risk factors for IH development after LT in the era of mammalian target of rapamycin (mTOR) inhibitors use. Methods Data on patients who underwent LT between 2015 and 2021 were retrospectively reviewed. The patients were divided into 2 groups (IH group and non-IH group) according to the postoperative occurrence of IH. Results We analyzed data from 878 patients during the study period, with 28 patients (3.2%) developing IH. According to multivariate analysis, body mass index exceeding 25 kg/m2 and the use of mTOR inhibitors within the first month after LT were the sole significant factors for both IH occurrence and the subsequent need for repair operations. Notably, a history of wound complications, a Model for End-stage Liver Disease score, and the timing of LT-whether conducted during regular hours or at night-did not emerge as significant risk factors for IH after LT. Conclusion Our study reveals a higher incidence of IH among obese patients following LT, often requiring surgical repair, particularly in cases involving mTOR inhibitor usage within the initial month after LT. Consequently, it is crucial to exercise increased vigilance, especially in obese patients, and exercise caution when considering early mTOR inhibitor administration after LT.

Abstract
INTRODUCTION There is insufficient evidence regarding the optimal regimen for ascites replacement after living donor liver transplantation (LT) and its effectiveness. The aim of this study is to evaluate the impact of replacing postoperative ascites after LT with albumin on time to first flatus during recovery with early ambulation and incidence of acute kidney injury (AKI). METHODS Adult patients who underwent elective living donor LT at Seoul National University Hospital from 2019 to 2021 were randomly assigned to either the albumin group or lactated Ringer's group, based on the ascites replacement regimen. Replacement of postoperative ascites was performed for all patients every 4 h after LT until the patient was transferred to the general ward. Seventy percent of ascites drained during the previous 4 h was replaced over the next 4 h with continuous infusion of fluids with a prescribed regimen according to the assigned group. In the albumin group, 30% of a total of 70% of drained ascites was replaced with 5% albumin solution, and remnant 40% was replaced with lactated Ringer's solution. In the lactated Ringer's group, 70% of drained ascites was replaced with only lactated Ringer's solution. The primary outcome was the time to first flatus from the end of the LT and the secondary outcome was the incidence of AKI for up to postoperative day 7. RESULTS Among the 157 patients who were screened for eligibility, 72 patients were enrolled. The mean age was 63 ± 8.2 years, and 73.0 % (46/63) were male. Time to first flatus was similar between the two groups (66.7 ± 24.1 h vs. 68.5 ± 25.6 h, p = .778). The albumin group showed a higher glomerular filtration rate and lower incidence of AKI until postoperative day 7, compared to the lactated Ringer's group. CONCLUSIONS Using lactated Ringer's solution alone for replacement of ascites after living donor LT did not reduce the time to first flatus and was associated with an increased risk of AKI. Further research on the optimal ascites replacement regimen and the target serum albumin level which should be corrected after LT is required.

Abstract
BACKGROUND This study aimed to evaluate recurrence-free survival (RFS) and overall survival (OS) after liver transplantation (LT) or liver resection (LR) for hepatocellular carcinoma (HCC) and perform subgroup analysis for HCC with high-risk imaging findings for recurrence on preoperative liver magnetic resonance imaging (MRI; high-risk MRI features). METHODS We included patients with HCC eligible for both LT and LR and received either of the treatments between June 2008 and February 2021 from 2 tertiary referral medical centers after propensity score-matching. RFS and OS were compared between LT and LR using Kaplan-Meier curves with the log-rank test. RESULTS Propensity score-matching yielded 79 patients in the LT group and 142 patients in the LR group. High-risk MRI features were noted in 39 patients (49.4%) in the LT group and 98 (69.0%) in the LR group. The Kaplan-Meier curves for RFS and OS were not significantly different between the 2 treatments among the high-risk group (RFS, P = 0.079; OS, P = 0.755). Multivariable analysis showed that treatment type was not a prognostic factor for RFS and OS ( P = 0.074 and 0.937, respectively). CONCLUSIONS The advantage of LT over LR for RFS may be less evident among patients with high-risk MRI features.

Abstract
OBJECTIVE The aim of this study was to identify safety and risk factors of living donor after pure laparoscopic donor right hepatectomy in a Korean multicenter cohort study. BACKGROUND Pure laparoscopic donor right hepatectomy is not yet a standardized surgical procedure due to lack of data. METHODS This retrospective study included 543 patients undergoing PLRDH between 2010 and 2018 in 5 Korean transplantation centers. Complication rates were assessed and multivariate logistic regression analyses were performed to identify risk factors of open conversion, overall complications, major complications, and biliary complications. RESULTS Regarding open conversion, the incidence was 1.7% and the risk factor was body mass index >30 kg/m 2 [ P =0.001, odds ratio (OR)=22.72, 95% CI=3.56-146.39]. Rates of overall, major (Clavien-Dindo classification III-IV), and biliary complications were 9.2%, 4.4%, and 3.5%, respectively. For overall complications, risk factors were graft weight >700 g ( P =0.007, OR=2.66, 95% CI=1.31-5.41), estimated blood loss ( P <0.001, OR=4.84, 95% CI=2.50-9.38), and operation time >400 minutes ( P =0.01, OR=2.46, 95% CI=1.25-4.88). For major complications, risk factors were graft weight >700 g ( P =0.002, OR=4.01, 95% CI=1.67-9.62) and operation time >400 minutes ( P =0.003, OR=3.84, 95% CI=1.60-9.21). For biliary complications, risk factors were graft weight >700 g ( P =0.01, OR=4.34, 95% CI=1.40-13.45) and operation time >400 minutes ( P =0.01, OR=4.16, 95% CI=1.34-12.88). CONCLUSION Careful donor selection for PLRDH considering body mass index, graft weight, estimated blood loss, and operation time combined with skilled procedure can improve donor safety.

Abstract
INTRODUCTION Given the global aging population, the average age of liver donors is increasing. This study aimed to evaluate the surgical outcomes of grafts from pure laparoscopic donor right hepatectomy (PLDRH) in liver donors aged > 50 years. METHODS The medical records of liver donors were retrospectively reviewed. The donors underwent conventional donor right hepatectomy (CDRH) from January 2011 to May 2019 or PLDRH from March 2016 to May 2019. We divided the donors into three groups: PLDRH donors aged ≥50 (n = 26; Group 1) and aged < 50 (n = 257; Group 2), and CDRH donors aged ≥50 years (n = 66; Group 3). RESULTS Operation time (p < .01) and hospital stay (p < .01) were significantly lower in Group 1 than in Group 3. Other postoperative outcomes of donors including graft anatomical variation, graft weight, graft-to-recipient weight ratio, and hepatic steatosis were similar among the three groups. Although no postoperative complications occurred in Groups 1 and 3, they were detected in 17 cases (6.6%) in Group 2. No postoperative complications were detected among the recipients. CONCLUSIONS PLDRH was feasible and safe in donors aged over 50 years, with outcomes similar to those for donors aged <50 years. PLDRH should not be avoided solely based on the donor's age ≥50 years.

Abstract
Acute kidney injury is considered an independent prognostic factor for mortality in patients with liver cirrhosis. Non-treated acute kidney injury can progress to hepatorenal syndrome with a poor prognosis. As suppression of tumorigenicity 2 (ST2) is a member of the interleukin-1 receptor family that aggravates inflammation and fibrotic changes in multiple organs, we measured soluble ST2 (sST2) level in the serum and urine of liver-transplant recipients at the time of transplantation. The serum sST2 level significantly increased in liver-transplant recipients with suppressed kidney function compared with that in recipients with normal function. In recipients with severely decreased liver function (model for end-stage liver disease score ≥ 30), the serum sST2 level was higher than that in recipients with preserved liver function (model for end-stage liver disease score ≤ 20, P = 0.028). The serum sST2 level in recipients with hepatorenal syndrome was higher than that in liver-transplant recipients without hepatorenal syndrome (P = 0.003). The serum sST2 level in patients with hepatorenal syndrome was higher than that in recipients without a history of acute kidney injury (P = 0.004). Recipients with hepatorenal syndrome and recovered kidney function showed higher sST2 levels than those who did not recover (P = 0.034). Collectively, an increase in the serum sST2 level reflects a decrease in both kidney and liver functions. Thus, measuring sST2 level at the time of liver transplantation can help predict renal outcomes.

Abstract
BACKGROUND Little is known about the performance of abbreviated MRI (AMRI) for secondary surveillance of recurrent hepatocellular carcinoma (HCC) after curative treatment. PURPOSE To evaluate the detection performance of AMRI for secondary surveillance of HCC after curative treatment. STUDY TYPE Retrospective. POPULATION A total of 243 patients (183 men and 60 women; median age, 65 years) who underwent secondary surveillance for HCC using gadoxetic acid-enhanced MRI after more than 2 year of disease-free period following curative treatment, including surgical resection or radiofrequency ablation (RFA). FIELD STRENGTH/SEQUENCE A 3.0 T/noncontrast AMRI (NC-AMRI) (T2-weighted fast spin-echo, T1-weighted gradient echo, and diffusion-weighted images), hepatobiliary phase AMRI (HBP-AMRI) (T2-weighted fast spin-echo, diffusion-weighted, and HBP images), and full-sequence MRI ASSESSMENT: Four board-certified radiologists independently reviewed NC-AMRI, HBP-AMRI, and full-sequence MRI sets of each patient for detecting recurrent HCC. STATISTICAL TESTS Per-lesion sensitivity, per-patient sensitivity and specificity for HCC detection at each set were compared using generalized estimating equation. RESULTS A total of 42 recurred HCCs were confirmed in the 39 patients. The per-lesion and per-patient sensitivities did not show significant differences among the three image sets for either reviewer (P ≥ 0.358): per-lesion sensitivity: 59.5%-83.3%, 59.5%-85.7%, and 59.5%-83.3%, and per-patient sensitivity: 53.9%-83.3%, 56.4%-85.7%, and 53.9%-83.3% for NC-AMRI, HBP-AMRI, and full-sequence MRI, respectively. Per-lesion pooled sensitivities of NC-AMRI, HBP-AMRI, and full-sequence MRI were 72.6%, 73.2%, and 73.2%, with difference of -0.6% (95% confidence interval: -6.7, 5.5) between NC-AMRI and full-sequence MRI and 0.0% (-6.1, 6.1) between HBP-AMRI and full-sequence MRI. Per-patient specificity was not significantly different among the three image sets for both reviewers (95.6%-97.1%, 95.6%-97.1%, and 97.6%-98.5% for NC-AMRI and HBP-AMRI, respectively; P ≥ 0.117). DATA CONCLUSION NC-AMRI and HBP-AMRI showed no significant difference in detection performance to that of full-sequence gadoxetic acid-enhanced MRI during secondary surveillance for HCC after more than 2-year disease free interval following curative treatment. Based on its good detection performance, short scan time, and lack of contrast agent-associated risks, NC-AMRI is a promising option for the secondary surveillance of HCC. EVIDENCE LEVEL 3. TECHNICAL EFFICACY Stage 2.

Abstract
To address the shortcomings of current hepatocellular carcinoma (HCC) surveillance tests, we set out to find HCC-specific methylation markers and develop a highly sensitive polymerase chain reaction (PCR)-based method to detect them in circulating cell-free DNA (cfDNA). The analysis of large methylome data revealed that Ring Finger Protein 135 (RNF135) and Lactate Dehydrogenase B (LDHB) are universally applicable HCC methylation markers with no discernible methylation level detected in any other tissue types. These markers were used to develop Methylation Sensitive High-Resolution Analysis (MS-HRM), and their diagnostic accuracy was tested using cfDNA from healthy, at-risk, and HCC patients. The combined MS-HRM RNF135 and LDHB analysis detected 57% of HCC, outperforming the alpha-fetoprotein (AFP) test's sensitivity of 45% at comparable specificity. Furthermore, when used with the AFP test, the methylation assay can detect 70% of HCC. Our findings suggest that the cfDNA methylation assay could be used for HCC liquid biopsy.

Abstract
Studies have shown that tuberculosis (TB) incidence is 20 to 70 times higher in solid organ transplantation recipients. Immunosuppression makes transplant recipients more vulnerable to infection and can interfere with the treatment. Our case report describes a patient who experienced immune reconstitution inflammatory syndrome (IRIS) and drug-induced liver injury (DILI) related to TB medications for disseminated pulmonary and hepatic TB. In addition to anti-TB medication, the patient received a high-dose steroid for IRIS and a change of anti-TB medication to a secondary regimen for DILI. This case illustrates various responses to anti-TB treatment in a liver transplant recipient and the necessity of closely monitoring immune suppression and liver function.

Abstract
Purpose The tablet form of tacrolimus is more convenient for drug ingestion than the capsule form. We examined the efficacy and safety of tacrolimus tablets and a satisfaction survey after formula conversion in liver transplant (LT) recipients. Methods This study was an open-label, prospective clinical trial for tacrolimus formula 1:1 conversion from capsule to tablet in 41 adult LT recipients with tacrolimus maintenance therapy of more than 1 month. The primary endpoint was incidence of biopsy-proven acute rejection (BPAR) within 24 weeks. Surveys 1 week before and 4 weeks after formula conversion were conducted for total daily dose of medication, number, scale of discomfort and satisfaction. Results The overall incidence of BPAR was 0% and there was no graft loss or patient death. The incidence of adverse effects was 34.1% (n = 14) after formula conversion. The most common severe adverse effect was abnormal liver function test (n = 5): biliary complications (n = 4) and alcoholic recidivism (n = 1). Total daily dose and number of tacrolimus doses were significantly lower after formula conversion (P < 0.05) without changes in trough level. According to survey analysis, there was no significant difference in discomfort and satisfaction scales from capsule to tablet conversion (P < 0.05). Conclusion The present study suggests that the new tablet formula can be a useful treatment option to maintain a consistent level of tacrolimus with a lower total daily dose and number in adult LT recipients.

Abstract
Background Pretransplant therapies such as rituximab and plasmapheresis have led to an increase in ABO-incompatible (ABOi) living donor liver transplantation (LDLT), thus helping to overcome organ shortages. This study evaluated the changes in anti-A/B titers and CD19 levels over time in patients undergoing ABOi LT and aimed to understand the effect of single-nucleotide polymorphisms (SNPs) in Fc gamma receptor (FcγR) on rituximab therapy. Methods Two SNPs of FCGR2A (131H/R) and FCGR3A (158F/V) were identified. The clinical data on 44 patients who underwent ABOi LDLT between May 2019 and October 2021 at Seoul National University Hospital were reviewed retrospectively. Results Following desensitization with rituximab and subsequent LDLT, the anti-A/B titer recovered within 1 week, but decreased thereafter. The CD19 level increased at 3 months after LT. The genotyping data for FCGR3A (158F/V) indicated that two patients had the V/V genotype, and 42 had the F/V genotype. In the genotyping data for FCGR2A (131H/R), 21 patients had the H/H genotype, three had the R/R genotype, and 20 had the H/R genotype. However, there were no significant differences in anti-A/B and CD19 levels, bacteremia rates, T cell-mediated rejection, antibody-mediated rejection, or the survival rate among the FCGR2A types. Conclusions There were significant changes in the anti-A/B titers and CD19 levels over time in each patient after ABOi LDLT. The difference in outcomes following LT according to the FcγR SNP type for rituximab was unclear. Further studies with larger sample sizes are needed to confirm the effect of FcγR SNPs on rituximab therapy.

Abstract
BACKGROUND AND AIMS Although the main action of human hepatitis B immunoglobulin (HBIG) is to neutralize hepatitis B virus surface antigen (HBsAg) in serum, HBIG is known to be localized in the cell. However, the effect of intracellularly located HBIG is poorly understood because of the low purity of conventional plasma-derived HBIG (cHBIG). We attempted to elucidate the mechanism of action of internalized HBIG using recombinant HBIG (lenvervimab). METHODS We used HBsAg producing cell lines, non-HBsAg cell lines and human HBsAg-producing hepatocytes. The autophagosome lysis pathway-related proteins Rab5, calnexin, giantin, and Rab7 were used to localize HBsAg and anti-HBs-IgG in the cytoplasm using Western blotting and confocal microscopy. RESULTS Intracellular anti-HBs-IgG (lenvervimab and cHBIG) transported via Fc receptor-mediated endocytosis increased the number of autophagosomes. However, there was no change in autolysis. HBsAg and anti-HBs-IgG co-localized in the multivesicular body and precipitated in the cytoplasm. HBsAg secretion into culture medium decreased after lenvervimab treatment. Simultaneously, the amount of cellular HBsAg increased in the cell lines but decreased in human hepatocytes. Furthermore, intracellular lenvervimab is not easily removed from HBsAg cell lines. CONCLUSIONS Lenvervimab decreases HBsAg secretion, and HBsAg antibody precipitation in the multivesicular body may play an important role.

Abstract
PURPOSE In living donor liver transplantation (LDLT), fatty liver adversely affects the outcome in donors or in recipients. The attenuation imaging (ATI) may be valuable for detecting fatty liver in potential liver donors. We aimed to investigate the role of ATI in screening liver donors. METHOD In this prospective study, potential liver donors undergoing MR examination, including proton MR spectroscopy (1H-MRS), were enrolled between January 2020 and December 2021 (study identifier: KCT0004486). All participants underwent ATI examinations to assess fatty liver disease. The reference standard for fatty liver was the hepatic fat fraction (HFF) on 1H-MRS, with 8% defined as the threshold for significant fatty liver. The correlation between attenuation coefficient (AC) and HFF was evaluated using Spearman's correlation coefficient. The diagnostic performance of AC for the detection of fatty liver disease was evaluated using receiver operating characteristic curve analysis. RESULTS A total of 102 participants (median age, 37 [range, 20-61] years; 65 men) were enrolled. Nineteen participants (18.6%) had significant fatty liver on 1H-MRS. AC significantly correlated with HFF on 1H-MRS (ρ = 0.674, P < 0.001), and was significantly higher in patients with HFF on 1H-MRS ≥ 8% than in patients with HFF on 1H-MRS < 8% (0.76 vs. 0.59, P < 0.001). By using the cutoff value of 0.66, the area under the curve of AC for the detection of significant fatty liver on 1H-MRS was 0.923 (95% confidence interval [CI]: 0.853-0.967), with sensitivity, specificity, and negative predictive values of 89.5% (95% CI: 66.9-98.7%), 83.1% (95% CI: 73.3-90.5%), and 97.2% (95% CI: 90.3-99.2%), respectively. CONCLUSIONS ATI showed good diagnostic performance with a high negative predictive value for the detection of significant fatty liver among potential liver donors.

Abstract
Hepatic artery thrombosis (HAT) after liver transplantation is associated with a marked increase in morbidity, leading to graft and patient loss. We evaluated the outcomes of adult living donor liver transplantation patients with HAT under an aggressive surgical intervention. A total of 1355 recipients underwent adult living donor liver transplantation at the Seoul National University Hospital. Surgical redo reconstruction for HAT was performed in all cases except in those with graft hepatic artery injury and late detection of HAT. Postoperative HAT developed in 33 cases (2.4%) at a median time of 3.5 days. Thirty patients (90.9%) underwent redo-arterial reconstruction. The survival rates in patients with HAT were similar to the rates in those without HAT (72.7% vs. 83.8%, p = 0.115). Although graft survival rates were lower in patients with HAT (84.8%) than in those without HAT (98.0%) ( p < 0.001), the graft survival rate was comparable (92.0% vs. 98.0%, p = 0.124) in the 25 patients with successful revascularization. Biliary complication rates were higher in patients with HAT (54.5%) than in those without HAT (32.0%) ( p = 0.008). In conclusion, the successful redo reconstruction under careful selection criteria saved the graft without retransplantation in 96.0% of the cases. Surgical revascularization should be preferentially considered for the management of HAT in adult living donor liver transplantation.

Abstract
Attenuated portal vein (PV) flow is challenging in pediatric liver transplantation (LT) because it is unsuitable for classic end-to-end jump graft reconstruction from a small superior mesenteric vein (SMV). We thus introduce a novel technique of an end-to-side jump graft from SMV during pediatric LT using an adult partial liver graft. We successfully performed two cases of end-to-side retropancreatic jump graft using an iliac vein graft for PV reconstruction. One patient was a 2-year-old boy with hepatoblastoma and a Yerdel grade 3 PV thrombosis who underwent split LT. Another patient was an 8-month-old girl who had biliary atresia and PV hypoplasia with stenosis on the confluence level of the SMV; she underwent retransplantation because of graft failure related to PV thrombosis. After native PV was resected at the SMV confluence level, an end-to-side reconstruction was done from the proximal SMV to an interposition iliac vein. The interposition vein graft through posterior to the pancreas was obliquely anastomosed to the graft PV. There was no PV related complication during the follow-up period. Using a jump vascular graft in an end-to-side manner to connect the small native SMV and the large graft PV is a feasible treatment option in pediatric recipients with inadequate portal flow due to thrombosis or hypoplasia of the PV.

Abstract
BACKGROUND Living donor liver transplantation (LDLT) is one of the most technically demanding and complicated procedures. However, unlike deceased donor liver transplantation, there is no suitable animal model for practicing LDLT. Herein, we propose a new liver segmentation method and a feasible pig LDLT model for practicing for LDLT in humans. METHODS Four Landrace pigs weighing 25, 25, 27, and 28 kg were used as donors and recipients to establish a partial liver transplantation model. Partial liver transplantation was performed using a right liver and a left liver, respectively, based on a new segmentation system compatible with that of humans. RESULTS We established a new segmentation system for porcine liver transplantation and a partial liver transplantation model. For right liver transplantation, 91 and 142 min were required to operate on the donor and recipient, respectively; for left liver transplantation, 57 and 104 min were required to operate on the donor and recipient, respectively. All pigs that underwent partial liver transplantation remained alive until the operation was completed. CONCLUSIONS It is expected that this new pig model based on the new segmentation system will be suitable as an educational tool for LDLT training and will replace the existing animal models for partial liver transplantation.

Abstract
PURPOSE Hepatobiliary phase (HBP) hypointense nodules without arterial phase hyperenhancement (APHE) on gadoxetic acid-enhanced MRI (GA-MRI) may be nonmalignant cirrhosis-associated nodules or hepatocellular carcinomas (HCCs). We aimed to characterize HBP hypointense nodules without APHE on GA-MRI by performing contrast-enhanced ultrasound using perfluorobutane (PFB-CEUS). METHODS In this prospective, single-center study, participants at high-risk of HCC having HBP hypointense nodules without APHE at GA-MRI were enrolled. All participants underwent PFB-CEUS; if APHE and late, mild washout or washout in the Kupffer phase were present, the diagnosis of HCC was established according to the v2022 Korean guidelines. The reference standard consisted of histopathology or imaging. The sensitivity, specificity, and positive/negative predictive values of PFB-CEUS for detecting HCC were calculated. Associations between clinical/imaging features and the diagnosis of HCC were evaluated with logistic regression analyses. RESULTS In total, 67 participants (age, 67.0 years ± 8.4; 56 men) with 67 HBP hypointense nodules without APHE (median size, 1.5 cm [range, 1.0-3.0 cm]) were included. The prevalence of HCC was 11.9% (8/67). The sensitivity, specificity, and positive and negative predictive values of PFB-CEUS for detecting HCC were 12.5%(1/8), 96.6%(57/59), 33.3%(1/3) and 89.1%(57/64), respectively. Mild-moderate T2 hyperintensity on GA-MRI (odds ratio, 5.756; P = 0.042) and washout in the Kupffer phase on PFB-CEUS (odds ratio, 5.828; P = 0.048) were independently associated with HCC. CONCLUSION Among HBP hypointense nodules without APHE, PFB-CEUS was specific for detecting HCC, which had a low prevalence. Mild-moderate T2 hyperintensity on GA-MRI and washout in the Kupffer phase on PFB-CEUS may be useful to detect HCC in those nodules.

Abstract
Purpose Total necrosis of hepatocellular carcinoma (HCC) achieved via locoregional treatment (LRT) is considered to indicate a lack of tumor viability. Nonetheless, there is insufficient evidence of recurrence after liver transplantation (LT) in patients with such a status. The aim of this study was to investigate the prognosis of patients diagnosed with totally necrotic nodules upon explant hepatectomy after LT. Methods We conducted a retrospective study of patients diagnosed with totally necrotic nodules after LT for HCC. A total of 165 patients with HCC who underwent living- or deceased-donor LT from 2000 to 2020 in our hospital were included. Results A total of 5 patients (3.0%) exhibited HCC recurrence during a median follow-up of 84 months (range, 4-243 months) after LT. The 5-year overall and recurrence-free survival rates of these patients were 92.8% and 92.2%, respectively. Four patients in the HCC-recurrence group (80.0%) died even after further treatment, including transarterial chemoembolization, surgery, and systemic treatment. Both univariate and multivariate analyses of clinicopathological factors identified a maximum diameter of the totally necrotic nodules of >5 cm as the only factor associated with tumor recurrence following LT (P = 0.005 and P = 0.009, respectively). Conclusion Total necrosis of HCC via LRT yielded excellent survival outcomes for patients undergoing LT. Nevertheless, patients with large tumors should be considered at high risk of recurrence after LT, suggesting the need for their active surveillance during the follow-up period.

Abstract
Purpose An increasing number of older patients now undergo liver transplantation (LT). Although the overall outcomes in older patients are not different from those of younger patients, there is no tool to predict LT prognosis in older patients. We hypothesized that a modified Charlson comorbidity index (mCCI) and 5-factor modified frailty index (mFI-5) can predict outcomes in older patients after LT. Methods This retrospective study included 155 patients (aged >65 years) who underwent LT at Seoul National University Hospital. The recipients were subcategorized into 2 groups based on the mCCI score and mFI-5: the low (0-1) and high (2-5) mCCI groups, and low (≤0.4) and high (>0.4) mFI-5 groups. The independent effect of each variable on post-LT survival was determined using the mCCI subgroup, age at transplantation, sex, Child-Turcotte-Pugh score, model for end-stage liver disease (MELD) score, and mFI-5 subgroup. Results The high-mCCI group (41 patients) showed significantly lower 1- and 3-month and 1-, 3-, and 5-year survival than the low-mCCI group. Using the Cox regression model, the mCCI, sex, and MELD score remained significant. The mFI-5 was not a significant factor to predict patients' survival. Conclusion The mCCI and MELD scores could be used to predict post-LT survival in older patients.

Abstract
Early allograft dysfunction (EAD) and acute kidney injury (AKI) are common and clinically important complications after liver transplantation. Serum lactate level at the end of surgery could predict EAD and neutrophil gelatinase-associated lipocalin (NGAL) is known as a biomarker for AKI after liver transplantation. The authors investigated whether the combination of these two laboratory tests could be used as an early predictor of these two complications of EAD and AKI. We reviewed cases undergoing living donor liver transplantation (n = 353). Lactate-adjusted NGAL level, a combination of these two predictors, was calculated as the sum of each value multiplied by the odds ratio for EAD or AKI. We evaluated whether this combined predictor at the end of surgery is significantly associated with both postoperative AKI or EAD. We compared the area under the receiver operating characteristic curve (AUC) between our multivariable regression models with and without NGAL, lactate, or lactate-adjusted NGAL. NGAL, lactate and lactate-adjusted NGAL are significant predictors for EAD and AKI. The regression model for EAD or AKI including lactate-adjusted NGAL showed a greater AUC (for EAD: odds ratio [OR] 0.88, 95% confidence interval [CI] 0.84-0.91; for AKI: OR 0.89, 95% CI 0.85-0.92) compared to the AUC of the models including lactate (for EAD: OR 0.84, 95% CI 0.81-0.88; for AKI: OR 0.79, 95% CI 0.74-0.83) or NGAL alone (for EAD: OR 0.82, 95% CI 0.77-0.86; for AKI: OR 0.84, 95% CI 0.80-0.88) or the model without lactate or NGAL (for EAD: OR 0.64, 95% CI 0.58-0.69, for AKI: OR 0.75, 95% CI 0.70-0.79). In conclusion, lactate-adjusted NGAL level at the end of surgery could be a reliable combined laboratory predictor for postoperative EAD or AKI after liver transplantation with a greater discriminative ability than lactate or NGAL alone.

Abstract
Biliary complications after living donor liver transplantation (LDLT) are the most common and intractable complications due to both surgical and nonsurgical factors. External biliary drainage (EBD), a surgical option to prevent biliary complications, has recently been adopted in the era of pure laparoscopic donor right hepatectomy, which may result in increased bile duct problems in the recipients. This study retrospectively reviewed the patients who underwent LDLT with duct-to-duct anastomosis between July 2017 and October 2020 to analyze the initial outcomes of EBD and to compare the incidence of biliary complications in adult LDLT recipients who underwent duct-to-duct anastomosis with or without EBD. Only patients who underwent pure laparoscopic donor hepatectomy were included in this study. The patients were divided into 2 groups according to the application of EBD. The median follow-up period was 28.5 months. The overall incidence of Clavien-Dindo grade IIIa biliary complications was 35.0% (n=14) in the EBD group and 50.7% (n=76) in the non-EBD group ( p = 0.08). The incidence of biliary leakage was 0% in the EBD group and 15.3% in the non-EBD group ( p = 0.01). The EBD-related complication rate, that is, involving retraction, accidental removal, and dislocation, was 40.0%. EBD implementation is effective in preventing biliary leakage after LDLT with a graft procured using the pure laparoscopic donor right hepatectomy method with duct-to-duct biliary anastomosis. However, efforts should be made to prevent EBD-related complications. Further studies are needed to establish appropriate selection criteria for EBD.

Abstract
Lagrangian models present several advantages over Eulerian models to simulate the transport of radionuclides in the aquatic environment in emergency situations. A radionuclide release is simulated as a number of particles whose trajectories are calculated along time and thus these models do not require a spatial discretization (although it is always required in time). In this paper we investigate the dependence of a Lagrangian model output with the grid spacing which is used to calculate concentrations from the final distribution of particles, with the number of particles in the simulation and with the interpolation schemes which are required because of the discrete nature of the water circulation data used to feed the model. Also, a Lagrangian model may describe the exchanges of radionuclides between phases (liquid and solid), which is done in terms of transition probabilities. The dependence of these probabilities with time step is analyzed as well. It was found that the optimum grid size used to calculate concentrations should be carefully checked, and that temporal interpolation is more significant than spatial interpolation to obtain a more accurate solution. A method to estimate the number of particles required to have a certain accuracy level is proposed. Finally, it was found that for low sediment concentrations and small radionuclide kd, exact equations for the transition probabilities should be used; and that phase transitions introduce a stability condition as in Eulerian models.

Abstract
Antithrombin-III (AT-III) concentrates have been used in the immediate postoperative period after liver transplantation to prevent critical thrombosis. We aimed to investigate more appropriate method for AT-III concentrate administration to maintain plasma AT-III activity level within targeted range. In this randomized controlled trial, 130 adult patients undergoing living-donor liver transplantation were randomized to either intermittent group or continuous group. In intermittent group, 500 international units (IU) of AT-III concentrate were administered after liver transplantation and repeated every 6 hours for 72 hours. In continuous group, 3000 IU of AT-III was continuously infused for 71 hours after a loading dose of 2000 IU over 1 hour. Plasma AT-III activity level was measured at 12, 24, 48, 72, and 84 hours from the first AT-III administration. The primary outcome was the target (80-120%) attainment rate at 72 hours. Target attainment rates at other time points and associated complications were collected as secondary outcomes. A total of 107 patients were included in the analysis. The target attainment rates at 72 hours post-dose were 30% and 62% in intermittent group and continuous group, respectively. (p=0.003) Compared to intermittent group, patients in continuous group reached the target level more rapidly (12 vs. 24 hours, median time, p<0.001) and was more likely to remain in the target range until 84 hours. For maintaining the target plasma AT-III activity level after living-donor liver transplantation, continuous infusion of AT-III seemed to be more appropriate compared to the conventional intermittent infusion regimen.

Abstract
Abstract
Liver cancer is a leading cause of death worldwide where somatic mutation plays a key role in tumorigenesis. As such, many recent researches have been conducted using DNA sequencing methods to study somatic mutations in liver cancer, such as whole-exome sequencing (WES), panel sequencing, and whole-genome sequencing (WGS). However, our understanding of genomic landscape of liver tumorigenesis has been limited by a low number of quality samples from diverse clinical contexts. Here, we explore comprehensive genomic landscape of liver cancer throughout its tumorigenesis using large-scale whole-genome sequencing of hepatocellular carcinoma (HCC) in various cancer stages and liver conditions. Total 500 patients of HCCs were enrolled in this study and whole-genome sequenced. 462 samples that passed quality control were included for final analysis. Most of the samples (427; 92%) were obtained from surgical resection and the rest (35; 8%) from liver transplantation. We used a standard WGS analysis pipeline from read mapping to variant calling of single-base substitution (SBS), indel, structural variation (SV), and copy number variation (CNV). Downstream data analyses were performed using in-house scripts with a particular focus on mutational signatures. To study how genome changes as HCC progresses, we classified samples into three groups by T stage: T1, T2, and T3/4. The number of samples for each group was 205 (44%), 222 (48%), and 35 (8%), respectively. There was no significant difference in the number of SBSs and indels, but the number of SVs was significantly higher in T3/4 (the mean of T1/2 vs. T3/4 = 51 vs. 93; p=0.001). Major mutational signatures were SBS5, 40 (both clock-like), 12 (unknown), and 22 (aristolochic acid) for SBSs and ID1, 2, 5 (all clock-like), and 3 (tobacco smoking) for indels. The proportion of ID2, characterized by 1bp deletion at homopolymer site, was increased in the samples of higher T stage (the mean proportion of T1/2 vs. T3/4=11% vs. 16%; p=0.01). The higher-stage samples also harbored more frequent whole-genome duplication (WGD) and loss of heterozygosity (LOH) (the frequency of WGD in T1/2 vs. T3/4=42% vs. 68%, p<0.001; the mean LOH fraction of T1/2 vs. T3/4=0.12 vs. 0.19, p<0.001). There was a significant enrichment of driver mutations of multiple genes (e.g., TP53, MTCP1, CCND3, etc.) in T3/4 group. Interestingly, in surgically resected T1 samples, ID2 proportion was the only significant contributor to early recurrence over tumor size, N stage, mean ploidy, and LOH fraction (n=199, p=0.05; Cox regression). Overall, we found that HCCs at different T stages exhibit some common and yet apparently distinguishing genomic features. We believe that the comprehensive genomic profile of HCC across cancer stages will provide deep insights into the genomic evolution of HCC and one day lend itself to clinicogenomic bases for better HCC management in the future.

Abstract
In recent years, laparoscopic techniques for liver resection or living donor hepatectomy have become common surgical methods. However, reports on laparoscopic surgeries for recipients are lacking. Our center has launched the minimally invasive living donor liver transplantation (LDLT) program in March 2020, which is led by two surgeons who are experienced in laparoscopic surgeries. Recently, we reported our first successful pure laparoscopic recipient explant hepatectomy and the first laparoscopic explant hepatectomy and robotic-assisted graft implantation. In this article, we introduce a series of minimally invasive surgical cases that were conducted by a single experienced surgeon to share our early experiences leading to our recent successes. We included 10 cases performed from June 2020 to May 2021 in our initial attempt at laparoscopic explant hepatectomy, graft implantation using midline incision, and robotic-assisted graft implantation surgery. The first four cases required open conversion during the liver mobilization process because of bleeding. The next two cases required open conversion to facilitate portal vein and hepatic artery division. We successfully performed pure laparoscopic explant hepatectomy in the last four cases. For the last case, we attempted to perform graft implantation using a robotic system, but bleeding required open conversion. All patients recovered without any significant acute postoperative problems and were discharged within 2 weeks. All 10 patients were followed up at outpatient clinics, and only one of the 10 patients had a late complication of LDLT. This study has shown that the minimally invasive approach in LDLT may be conducted safely without significant complications if it is performed by highly experienced surgeons working in high-volume centers.

Abstract
BACKGROUND/PURPOSE Since minimally invasive surgery has been incorporated in overall surgery, pure laparoscopic technology is involved in most hepatectomies, including right hepatectomy, in patients with hepatocellular carcinoma (HCC). However, its feasibility and safety in right hepatectomy are still controversial owing to the limited literature. This study aimed to compare the short- and long-term outcomes of pure laparoscopic right hepatectomy (PLRH) with those of open right hepatectomy (ORH) in patients with HCC. METHODS The prospectively collected medical records of 327 patients with HCC who underwent right hepatectomy between January 2010 and April 2020 at Seoul National University Hospital were retrospectively reviewed. We performed 1:1 propensity score matching between the PLRH and ORH groups. The primary end point was short-term outcomes, including hospital stay, blood loss, and morbidity; the secondary end point was long-term outcomes, including overall and recurrence-free survival. RESULTS Forty-nine patients were included in each group. Patients who underwent PLRH had a shorter postoperative hospital stay than those who underwent ORH (12.2 vs 8.9 days; P < .001). The requirement for blood transfusion was significantly lower in the PLRH group than in the ORH group (10.2% vs 2.0%; P = .010). The operative time (P = .479) and proportion of major complications (P = .487) were comparable between the groups. There were no significant differences in overall survival (P = .524) and the recurrence-free survival rate (P = .576) between the groups. CONCLUSIONS Postoperative outcomes, including oncological outcomes, were comparable between PLRH and ORH, showing that PLRH can be a safe and feasible option to replace ORH in patients with HCC.

Abstract
This study aimed to classify the anatomical types of biliary strictures, including intrahepatic biliary stricture (IHBS), after living donor liver transplantations (LDLTs) using right liver grafts and evaluate their prognosis. Among 692 adult patients who underwent right liver LDLT, 198 recipients with biliary strictures (28.6%) were retrospectively reviewed. Based on data obtained during the first cholangiography, the patients' biliary strictures were classified into the following three types according to the levels and number of branches involved: Types 1 (anastomosis), 2 (second-order branch [a, one; b, two or more; c, extended to the third-order branch]), and 3 (whole graft [a, multifocal strictures; b, diffuse necrosis]). IHBS was defined as a nonanastomotic stricture. Among the 198 recipients with biliary strictures, the IHBS incidence rates were 38.4% ( n = 76). The most common type of IHBS was 2c ( n = 43, 56.6%), whereas Type 3 ( n = 10, 13.2%) was uncommon. The intervention frequency per year significantly differed among the types (Type 1, 2.3; Type 2a, 2.3; Type 2b, 2.8; Type 2c, 4.3; and Type 3, 7.2; p < 0.001). The intervention-free period for more than 1 year, which was as follows, also differed among the types: Type 1, 84.4%; Type 2a, 87.5%; Type 2b, 86.7%; Type 2c, 72.1%; and Type 3, 50.0% ( p = 0.048). The graft survival rates of Type 3 (80.0%) were significantly lower than those of the other types ( p = 0.001). IHBSs are relatively common in right liver LDLTs. Although Type 3 IHBSs are rare, they require more intensive care and are associated with poorer graft survival rates than anastomosis strictures and Type 2 IHBS.

Abstract
BACKGROUND Due to impaired cell-mediated immunity, solid organ transplantation (SOT) recipients are at increased risk of developing nontuberculous mycobacterial pulmonary disease (NTM-PD). However, the clinical course of NTM-PD in SOT patients and the impact of SOT on the prognosis of NTM-PD remain unclear. METHODS We analyzed patients who developed NTM-PD after receiving SOT between January 2001 and December 2020, at a tertiary referral hospital in South Korea. Baseline characteristics, clinical course, and prognosis were evaluated. Propensity score-matched analysis was performed to assess the impact of SOT on long-term survival in patients with NTM-PD. RESULTS Among 4,685 SOT recipients over 20 years, 12 patients (median age, 64 years; interquartile range [IQR], 59-67 years; men, 66.7%) developed NTM-PD. Seven (58.3%) and five (41.7%) patients underwent kidney and liver transplantation, respectively, before the diagnosis of NTM-PD. The incidence of NTM-PD was 35.6 cases per 100,000 person-years among kidney transplant recipients and 28.7 cases per 100,000 person-years among liver transplant recipients. The median time between transplantation and the diagnosis of NTM-PD was 3.3 (IQR, 1.5-10.8) years. The most common mycobacterial species was Mycobacterium avium (50.0%). Antibiotic treatment was initiated in five (41.7%) patients, and two patients (40.0%) achieved microbiological cure. Two patients died during a median follow-up of 4.2 (IQR, 2.3-8.8) years and NTM-PD was assumed to be the cause of death in one patient. When matched to patients without a history of SOT, patients with a history of SOT did not show worse survival (P value for log-rank test = 0.62). CONCLUSION The clinical course of NTM-PD in SOT recipients was comparable to that of patients without SOT, and SOT did not increase the risk of all-cause mortality in patients with NTM-PD.

Abstract
Adrenal and spinal metastases of hepatocellular carcinoma (HCC) are rare entities with significant morbidity and mortality, particularly after liver transplantation (LT). We report a case of a 49-year-old man who underwent LT for hepatitis B-related end-stage liver disease and HCC (single 4.5 cm lesion [T1N0], without vascular invasion) in 2016. Eighteen months later, adrenal metastasis and hepatitis B seropositive conversion were developed with normal serum tumor. Adrenal metastasis was treated with radiation therapy (RT) and hepatitis B showed spontaneous seronegative conversion. However, 35 months later, spinal metastasis occurred with elevation of the protein induced by vitamin K absence or antagonist-II (PIVKA-II) level (197 mAU/mL), along with hepatitis B seropositive conversion. After sorafenib, sequential regorafenib with RT led to partial response of the spinal lesions, along with hepatitis B seronegative conversion and normal PIVKA-II levels. After 9 months of regorafenib combined with RT, two recurrent lesions were found, as well as hepatitis B seropositive conversion and lesions were treated with transarterial chemoembolization. The patient survived for more than 71 months after LT and 53 months after recurrence under various combinations of therapy. Combined systemic and locoregional therapies can be a treatment option for HCC recurrence, even in LT patients.

Abstract
Purpose De novo malignancy is common after liver transplantation (LT); however, there are limited reports on the clinical outcomes of gastric cancer surgery after LT. Our study aimed to investigate the feasibility and safety of gastric cancer surgery after LT. Methods Seventeen patients underwent gastric cancer surgery after LT at a single institution between January 2013 and June 2021. We retrospectively collected data on surgical complications, survival, and recurrence status of these cases. Results Fifteen patients (88.2%) underwent curative gastrectomy, with 10 open distal (66.7%) and 5 laparoscopic distal (33.3%) gastrectomies. Surgical and severe complication rates were 3 of 15 (20.0%) and 1 of 15 (6.7%), respectively. There were no significant differences between laparoscopic (33.3%) and open surgery (66.7%) in terms of operation time and complication rate. No surgery-related mortalities occurred. Immunosuppressants could be maintained without difficulty, and no suspicious acute rejection was identified during the perioperative period. There was 1 recurrence after curative surgery (recurrence rate, 6.7%), and the 5-year cancer-specific survival rate after curative surgery was 93.3%. Conclusion Laparoscopic gastrectomy can be safely done even after LT in terms of postoperative complications and graft safety.

Abstract
BACKGROUND The impact of renal replacement therapy (RRT) on the long-term survival outcomes of pediatric liver recipients remains controversial. METHODS A total of 224 patients aged <18 years, who underwent liver transplantation (LT), were divided into two groups: patients who underwent renal replacement therapy (RRT) (group R, n = 25, 11.2%) and those who did not (group N, n = 199, 88.8%). The posttransplant patient survival outcomes according to RRT use constituted the primary end-point. RRT was initiated preoperatively in 12 patients (48.0%) and postoperatively in 13 [early: <6 months after LT (n = 5, 20.0%) and late: ≥6 months after LT (n = 8, 32.0%)]. The indications for RRT included liver disease involving the kidney (44.0%) and hepatorenal syndrome (56.0%). RESULTS The age at the time of LT (71.6 vs. 19.1 months) was higher, the pediatric end-stage liver disease score was lower (9.9 vs. 21.2), and the duration of hospitalization posttransplantation (41.0 vs. 27.0 days) was longer, while the rates of hepatic artery thrombosis (8.0% vs. 3.5%) were higher in group R (p < .05). The number of patients (60.0% vs. 93.0%; p < .001) and graft survival rates (68.0% vs. 93.0%; p < .001) were significantly lower in group R. Multivariate analysis revealed that posttransplant RRT and hepatic artery complications were risk factors for patient survival outcomes. Renal function was recovered in 7 patients (28.0%) in group R, and 9 (36.0%) eventually underwent kidney transplantation. CONCLUSION The survival outcomes of children requiring posttransplant RRT were significantly worse than those of children, who did not undergo RRT. Physicians should pay meticulous attention to patients requiring post-LT RRT.

Abstract
Purpose Liver grafts from donors with HBV infection contributed to expanding the donor pool under the hepatitis B immunoglobulin and antiviral agents (nucleos(t)ide analogues) in the HBV-endemic area. We report long-term outcomes of liver transplantations (LTs) using grafts from donors with active or chronic HBV infection. Methods Overall, 2,260 LTs performed in 3 major hospitals in Seoul from January 2000 to April 2019 were assessed for inclusion. Twenty-six grafts (1.2%) were obtained from HBsAg (+), HBeAb (+), or HBcAb (+) donors, and recipient outcomes were retrospectively reviewed. Donor and recipient demographics and transplantation outcomes were analyzed. Results Sixteen deceased donor LTs were performed using active HBsAg (+) grafts. Ten other LTs were sourced from 10 living donors. There was no significant difference in survival in patients who received deceased donor LTs compared with that in those who underwent LT with non-hepatitis virus-infected grafts. Fourteen patients who were followed up for >5 years were stable, and no difference in hepatocellular carcinoma recurrence rate was observed 5 years after transplantation between transplants from donors with and those without HBV. Conclusion Considering long-term outcomes, liver grafts from donors with active HBV replication can be safely used for LT.

Abstract
There is much controversy regarding enhanced recovery for recipients of liver transplants from deceased and living donors. The objectives of this Review were to summarise current knowledge on individual enhanced recovery elements on short-term outcomes, identify key components for comprehensive pathways, and create internationally accepted guidelines on enhanced recovery for liver-transplant recipients. The ERAS4OLT.org collaborative partnered by the International Liver Transplantation Society performed systematic literature reviews on the effect of 32 relevant enhanced perioperative recovery elements on short-term outcomes, and global specialists prepared expert statements on deceased and living donor liver transplantation. The Grading Recommendations, Assessment, Development and Evaluations approach was used for rating of quality of evidence and grading of recommendations. A virtual international consensus conference was held in January, 2022, in which results were presented, voted on by the audience, and discussed by an independent international jury of eight members, applying the Danish model of consensus. 273 liver transplantation specialists from 30 countries prepared expert statements on elements of enhanced recovery for liver transplantation based on the systematic literature reviews. The consensus conference yielded 80 final recommendations, covering aspects of enhanced recovery for preoperative assessment and optimisation, intraoperative surgical and anaesthetic conduct, and postoperative management for the recipients of liver transplants from both deceased and living donors, and for the living donor. The recommendations represent a comprehensive overview of the relevant elements and areas of enhanced recovery for liver transplantation. These internationally established guidelines could direct the development of enhanced recovery programmes worldwide, allowing adjustments according to local resources and practices.

Abstract
BACKGROUND/PURPOSE Donor-type ABO blood group antigens (dABOAgs) have been detected in ABO-incompatible adult living donor liver transplantation (ABOi ALDLT) grafts, but their fate and role in ABOi ALDLT rejection remain uncertain. METHODS The 0-day, <1-month, and 1-year serial liver graft biopsies from 30 ABOi ALDLT recipients were retrospectively evaluated. ABO antigen expression was quantitatively and serially measured by the mean number of positively stained vascular structures (endothelium of the capillaries, arteries, hepatic veins, and portal veins) within the portal tracts (sS). RESULTS The dABOAg sS counts of 0-day, <1-month, and 1-year liver graft biopsies (32.3, 20.8, and 20.6, respectively) decreased significantly (p < .001). Early rejection in the <1-month biopsy was observed in 8/30 (26.7%) recipients, four (13.3%) of whom showed antibody-mediated rejection. The sS counts tended to rebound in grafts showing early rejection, with minimal changes from the 0-day to <1-month period, but increased to pre-transplantation levels after 1 year, compared to that in grafts without early rejection (36.0, 20.4, 19.6 vs. 23.7, 21.9, 23.0, respectively; p = .040). CONCLUSIONS While dABOAg expression decreased after ABOi ALDLT, recipients showing early rejection showed sustained graft dABOAg expression. Therefore, dABOAg expression may be involved in the mechanism of accommodation in ABOi transplantation.

Abstract
BACKGROUND Accurate volumetric evaluation of donors' livers before surgery is crucial for successful living-donor liver transplantation. However, there are few studies on the volumetric evaluation in the recently popularized pure laparoscopic donor hepatectomy method, in contrast to the number of studies for conventional donor hepatectomy. We aimed to analyze the difference between estimated graft weight and actual graft weight in pure laparoscopic donor right hepatectomy (PLDRH) and conventional donor right hepatectomy (CDRH) procedures. MATERIAL AND METHODS The medical records of 612 donors who underwent right hepatectomy in living-donor liver transplantation between January 2014 and December 2020 were retrospectively reviewed. The CDRH group targeted patients from January 2014 to October 2015, and the PLDRH group targeted patients from March 2016 to December 2020. RESULTS There were 119 and 376 donors who underwent CDRH and PLDRH, respectively. Although there was no significant difference in the estimated graft weights (P=0.994) and actual graft weights (P=0.489) between the groups, the estimated graft weights were significantly higher than the actual graft weights in both groups. However, the estimated graft weight and actual graft weight showed linear correlations in both the CDRH (r=0.81, P<0.001) and PLDRH (r=0.76, P<0.001) groups, with the CDRH group having greater linearity. CONCLUSIONS The estimates of graft weight were similar between the 2 groups. However, since the actual graft weight tended to be smaller in the PLDRH group, this should be considered before surgery.

Abstract
Mesenchymal hamartoma of the liver (MHL) is a rare benign tumor that often presents in early childhood, and it rarely occurs in adulthood. Aberrant development of the portal tract is a known cause of MHL. Although limited information is available on the natural course of MHL, malignant transformation has been reported in a few cases. Here, we report a case of a 26-year-old female with intrahepatic cholangiocarcinoma secondary to unresected MHL. The patient underwent resection of the hepatic mass, which was diagnosed as MHL at 2 years of age, due to an increase in mass size and a suspicion of malignant transformation during work-up. Histopathology confirmed intrahepatic adenosquamous carcinoma in the background of MHL, with a T2N0M0 pathological stage (stage II). The surgical margin was free from tumor cells. The patient fully recovered postoperatively and started receiving adjuvant chemotherapy. Previous case reports have only reported about the development of undifferentiated embryonal sarcoma or angiosarcoma as malignant transformation of MHL. Cases of other malignancies have not been published; however, it is difficult to rule out the occurrence of various malignancies related to the portal tract when considering the pathogenesis of the disease. To the best of our knowledge, this is the first case report of adenocarcinoma of bile duct origin secondary to MHL. This case report suggests that aggressive surgical management should be considered after the initial diagnosis of MHL.
